MOWING-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 755,226, dated March22, 1904. Application filed July 27,1903. Serialbl'o.167,293. (Nomodel.)

To all whom it may concern:

Be it known that I, NORMAN F. GRAvEs, a citi- Zen of the United States,residing at Alma, in the county of Marion and State ofIllinois, haveinvented certain new and useful Improvements in Mowing-Machines; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

My invention relates to mowers and reapers, and has for its object toprovide a device of this class which is particularly simple in itsconstruction, easy and positive of operation.

A further object of my invention is to pro vide a mower having areciprocating cutterbar which can be raised into substantially avertical position and which can be reciprocated when carried out of ahorizontal position, as would be necessary when cutting frdm a slighthill or rise in the ground.

A further object of my invention is to provide a novel means for raisingor lowering the cutting apparatus while in a horizontal position.

With these and other objects in view my invention consists in the novelmeans of connecting and operating the cutting apparatus.

My invention also consists in the novel means of adjusting the height ofthe cutting apparatus.

My invention also consists in certain other novel features ofconstruction and incombination of parts, which will be first fullydescribed and afterward specifically pointed out in the appended claims.

Referring to the accompanyingdrawings, Figure 1 is a plan view of myinvention. Fig. 2 is a front elevation of the same. Fig. 3 is a sideelevation with one wheel removed. Fig. 4 is a longitudinal verticalsection on line 4 4 of Fig. 1. Fig. 5 is a like view showing manner ofadjusting the height of cutting apparatus. Fig. 6 is a detailedperspective View of the connections between the cutter-bar and the bodyof the machine.

Like characters of reference indicatethe same parts throughout theseveral figures, in which V 1 isthe mower, having the wheels 2 and 3,said wheel 3 being corrugated at 4, as shown in Figs. 1,2, and 3.

5 and 6 indicate the main longitudinal framepieces, to which the axle 7is secured.

8, 9, and 10 indicatethe transverse framepieces secured to saidlongitudinal framepieces. I

11 indicates the tongue secured in the clip 12 under the frame-piece 8,and 13 is the drivers seat secured to frame-piece 10.

14 and 15-indicate two rocking levers fulcrumed at 16 to the rod 17 andcarrying the small rollers 18 and 19 between the said levers. Said rod17 passes through a guide 20, secured to the frame-piece 6, and said rodis connected at its inner end to a lever 21, to which lever is securedan operating-lever 22, fulcrumed on the frame-piece 10. Secured to saidrocking levers 14-and 15 at 23 is a rod 24, which passes into a guide25, secured to frame-piece 5, and connected to said rod at 26 is arocking lever 27, fulcrumed on brace-piece 27'. Pivoted to said rockinglever is a link 28, whichconnects with a vertical rocking lever 29,fulcrumed to the bracket 30, secured to the side of the frame-piece 5.Connected to the bottom of said vertical rocking lever at 31 is thereciprocating cutter 32, suitably secured to the finger-bar'33, so as tobe capable of. a reciprocating movement". Said finger-bar 33 is rigidlysecured to an arm 34, substantially at right angles thereto, said armbeing pivoted to a bracket 35 under the frame piece 5,

Fig. 6, and pivoted to said arm at 36 is a link 37, pivoted at its upperend to operatinglever 38, fulcrumed at 39 to frame-piece 5, said leverextending rearwardly, so as to be capable of operation by the foot ofthe driver. A projection 40 or other suitable holding means on theframe-piece 5 is employed to hold said lever depressed.

Secured to a bracket 41 at rear of machine is a vertical operating-lever42, to which is pivoted a rod 43, Figs. 4 and 5, and secured to theforward end of said rod and extending therefrom is a wedge member 44,adapted to operate between the tongue 4 and the bracketpiece 35.

Having thus set forth the several parts of my invention,its operation isas follows: When the operating-lever 22 is in position shown in Fig. 1,the rollers 18 and 19 between the rocking levers 14 and 15 are inengagement with the corrugations 4 on the wheel 3. By moving said leveraway from the seat 13 the said rocking levers and rollers are carriedout of engagement with the wheel 3 by reason of said lever 22 actingupon lever 21 and rod 17. This throws the cutting apparatus out ofconnection with the driving-wheel 3 and stops the reciprocating of thecutter-bar, which is operated by said rod 24 rocking the horizontallever 27 and the vertical lever 29, said lever acting directly upon thecutting-bar.

In order to carry the cutter apparatus up out of position, as shown at Ain dotted lines in Fig. 2, the lever 38 is depressed by the foot of thedriver and carried down under the stop 40. This raises the forward endof said lever and swings the arm 34 up on its pivot, as shown in dottedlines in Fig. 2. Should, however, occasion require the cutting apparatusto be raised into the position shown in dotted lines at B in Fig. 2 orin any intermediate position, the lever 38 is depressed with the foot ofthe driver and held in the desired position, or I could employ suitablestops for holding said lever at dififerent points, and it will be notedthat the cutting apparatus will continue to operate when in said raisedposition, whereby it is possible to operate the machine on a hill or toadapt the cutting apparatus to any rises or unevenness in the land.

In order to adjust the distance of the cutting apparatus from theground, so that the machine can out different lengths, I employ thelever 42 to operate the wedge member 44 between the tongue 11 and thebracket 35, as shown in Figs. 4 and 5.

Having thus fully described my invention, I do not'wish to be understoodas limiting myself to the exact construction herein set forth, asvarious slight changes could be made therein by those skilled in the artwhich would fall within the limit and scope of my inven tion, and Iconsider myself clearly entitled to all such changes and modifications.

What Iclaim as my invention, and desire to secure by Letters Patent ofthe United States,

1. In a mower, the combination of a body, a cutting apparatus, an armsecured to said cutting apparatus and pivoted. to said body, adriving-Wheel having its inner face provided with aseries ofcorrugations, a rocking lever adapted to be rocked by said corrugations,a rod carrying said rocking lever. and means for moving said rod androcking lever out of engagement with said corrugations, a reciprocatingrod secured to said rocking lever adapted to to be reciprocated thereby,a vertical rocking lever connected to said cutting apparatus and adaptedto be rocked by said reciprocating rod through intermediate connections,and means for swinging said cutting apparatus and arm up upon the pivotof said arm.

2. In a mower, the combination of a body, a cutting apparatus, an armsecured to said cut ting apparatus and pivoted to said body at a pointconsiderably above said cutting apparatus, a rocking lever fulcrumedabove said pivotal point of said arm, and means for rocking said rockinglever, a link pivoted to said arm, an operating-lever connected to saidlink, the whole arranged whereby said arm and cutting apparatus areswung up on the pivot of said arm by said operating-lever, and thecutting apparatus operated by said rocking lever when said cuttingapparatus is in a position raised above the horizontal.

3. In a mower, the combination of a body, a cutting apparatus securedthereto, means for operating said cutting apparatus, a tongue pivoted tosaid body, a wedge member and rod for carrying the same, and means formoving said rod to drive said wedge under said tongue to raise the afterend thereof.

In. testimony whereof I afiix my signature in presence of two witnesses.
